到目前为止，人们已经提出了各种双电层电容器的等效电路模型。RC电路的多级连接是模拟EDLC充放电特性的典型模型。然而，由于高能量密度型EDLC的静电容量高达几千F，在实际测量中出现了对常规电容器几乎没有影响的现象。为了克服这一困难，在本文中，我们利用考虑了静电容量的电压相关性的非线性模型来建立等效电路模型。通过各种仿真实验并与实验结果进行比较，验证了该模型的有效性。
Various models for the equivalent circuit of EDLC (Electric Double Layer Capacitor) have been presented so far. The multi-stage connection of RC circuit is a representative model to simulate the EDLC's charge-discharge characteristic. However, since high energy density type EDLC for electric power storage has the electrostatic capacity of thousands F, the phenomenon of being almost uninfluential for the case of conventional capacitor appears in an actual measurement notably. To overcome this difficulty, we develop an equivalent circuit model using a nonlinear model that considers the voltage dependency of the electrostatic capacity in this paper. After various simulations and comparison with experimental results, we confirmed the effectiveness of the proposed model.
